"-" + Enter would raise an error in Task Editor

[Song Yangyu]

GTG revno: 1140

I think we designed this method for the easy key-in of the subtask: inside the task editor, for any line starting with -, pressing enter would automatically create new subtask.

But there's a bug: simply key in "-", then press enter key.
You can see the error.
